B e it known that I, Puur E. HoL'r, a citizen ofthe United States, andre'lsidingat 836 West Poplar street, in .the f city `-o f Stockton,`county'of San Joaquin, and State of California, have invented certain new and useful Improvements', in.' .Two-Wheeled ADump-Wagons; and Idohereby declare the following ,to bea full, gclear, and exact description of the :said '.invention, .such as will enable: others skilled in the art Vto .which it most g nearlyrappertains, to make, ,n.se, and

This invention relates dump wagons and consists ofthe novel ,constructionnd arrangementof the parts as hereinafter. described.

The object of ,this invention projduce atwojwheel bottom dump wagon particularly adapted to, be drawn in either 4di-l rection, .to be, trailed behind. road tractors, andto --be-,coupled together inrtrainscapable pfturningin. a short radiuscwithout cramplroadly,the inventioiiiconsistis of a :two wheeled truck with its axlelocated approximately across .the centerfof ,the wagon frame ;u spring drawheads located at each end of the wagon frame and provided with a collapsible trundle` jackthereunder adaptedV to maintain thelevel .ofthe frame when4 the wagon iS uncoupl'ed, an angular inclosed body built upon the wagon frame and having a double chute bottoml closed by hinged doors operated by a compensated chain tackle and winch rotated by a worm gear operated by a hand lever at the side of the wagon.

In the drawings :-F igure 1 is a side elevation illustrating a dump wagon constructed in accordance with this invention. Fig. 2 is a plan View from above the same.

In detail, 'the construction consists of the supporting Wheels 1, of suitable construction to meet road conditions and support the load on the axle. e on the transverse axle 2, mounted in the journal boxes 3. The body of the wagon is supported from the axle by the yokes 4, riveted to the side plates 5 of the wagon frame. The wagon frame .iscomposed of the side plates 5, joined across the ends by similar plates.

The drawheads comprise the draft bars 6 fixed at yone end 7 to the end plates of the wagon frame, and joined at their outer ends "Specication'of Letters Patent. A Apiniafifon iea July 1, 1909. serial No. 505,385.

The Wheels are mounted Two-WHEELED DUMP-WAGON.

The draft bars are braced yby the side stays .12, extending- `from the blocks 8 to their respective corners.-

The jacks' comprisetheswinging frame 13, hinged to the wagon' frame, asat 14, and converging to the axis of the wheel -15, journaled therein; andV an adjustable column l.comprising the hand Wheel and'stem 16, threaded nfthe 'yoke 17, pivoted on the axle of the trundle 15, and provided with the pointed head adapted,toengage a notch (not shown) in the 'underside of the'block 8, whenin operative position. .When not in use,"t hlejack iscollapsible and suspended bytlney hook 18, beneath the drawhead, as shownin n.

The body of the wagonis composed of the side panels 19, and the end panels 20,5joined at the cornersby the angle bars 21,V to which they are both riveted. The topf of the body is reinforced by the angle frame; 22, riveted to the bodyy panels. The side panels are riveted to the side plates 5, atthe bottom and become a rigid part ofthe wagon frame. The bottom of the wagon body is composed Vof the inclined plates, 23 and 24, riveted to the side panels. These plates form' an arch over the axle, and cooperate with the inbent ends 25, of the end panels to form two chutes in the bottom closed by the swinging doors 26 and 27, hinged tothe bottom at the points 28. These doors are operatedby the chains 29 and 30, attached to their respective doors on both sides of the wagon body, and passing over the sheaves 31 and 32, respectively, they are Ijoined to opposite ends of the compensating bar 33, which is pivoted at its center to the chain 34,which passes over the sheaves 35, and is wound about the Winch rod 36, which 'is bracketed to the wagon body and is rotated by the worm gear 37 actuated by the hand lever 38, which is mounted on the side of the wagon. The drawheads are braced to the wagon-'body by top downward to the draft'bars vpatent to be filed later.

One of the wheels 1 is iixed upon the axle 2, which rotates freely in the journals 3; the other wheel is journaled on the axlel upon which it rotates to allow for diiterential in rounding corners. |This feature will form part of .a separate application for As illustrated, this wagon is adapted lto an all-steel construction very desirable in this class of wagons. Being supported upon two wheels only, atrain of these wagons is capable of following the turns and inequalities encountered in the ordinary road, and because of its lateral fiexibility such a train can be turned within a very short radius.

The prime advantage of this invention is `the adaptability Aof the wagon to be drawn inA either direction. It often happens that there is not suiiicient space to turn a wagon train, and under such circumstances the tractor can be uncoupled and hitched to the other end of the train. This condition is often met with where it is necessary to unload over elevated bunkers, or within a limited space, such as gravel pits, drifts,

narrow roadways, etc.

Having thus described this invention what is claimed and desired to secure by Letters Patent is 1. The combination with a wagon body,` of a draw head comprising two parallel bars secured at one end to the wagon body, a block rigidly secured between the outer ends of said bars, a spring and a link surrounding said block and spring and having its side arms slidably mounted between said block Aand bars, said link having its forward end extending beyond said vblock to form a coupling loop.

2. The combination witha wagon body, of

a draw head comprising two bars secured at onevend to the wagon'body, a block rigidly secured between the outervends of said bars and having groovestormed in its sides, a spring abutting the inner end of said block, and a link surroundingv said block and spring and having its side arms disposed to slide in said grooves, said link'having its outer end extending beyond said block to form a coupling loop.

, 8. The combination with a wagon body, of a draw head comprising two bars secured at one end to the wagon body, a block rigidly secured between the outer ends of said bars and having grooves formed in its sides, a spring abutting the inner end of said block, and a link surrounding said block and spring and having its side arms disposed to slide in said grooves and itsQuter end extending beyond said block to form a coupling loop, and side stays extending from said block to the corners of the wagon frame.l

4. The combination with a wagon body, oi

a draw head comprising two bars secured at l one end to the wagon body, a block rigidly secured between the outer ends of said bars and having grooves formed in its sides, a spring abutting the inner end of said block, a link surrounding said block and spring and having its side arms disposed to slide in said grooves and its outer end extending beyond said block to form a coupling loop, side stays extending from said block to the corners of lthe wagon Jframe, and a top stay extending from said block to the wagon body. l

Y In testimony whereof, I have hereunto set my hand this' 21st day of 'J une 1909.
